El Reg just published a useful article on SCION, although the headline is a little clickbaity.

A few of my own thoughts on the matter:
- The Internet, per se (the network of things which speak to each other using IPv4, IPv6, and their successors at layer 3), won't last forever.
- Whatever follows the Internet will have to be developed and adopted, and that will take a lot of work over a long (meaning probably 30+ years) time.
- Most projects fail.
- That means that, whatever the merits and demerits of SCION, _many_ projects like it need to be underway, temporally overlapping.

Switzerland built a secure alternative to BGP. The rest of the world hasn't noticed yet

@woody I agree, Bill. It’s good to have many different projects exploring what could work in the future. It will be interesting to see where this all goes!
